2. 1. On the Analysis and Fault-Diagnosis Tools for Small-Scale Heat and Power Plants

   Author : Jaime Arriagada; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; genetic algorithms; neural networks; fault diagnosis; maintenance; availability; reliability; energy analysis; combined heat and power; Methods and tools; small scale;

   Abstract : The deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. READ MORE

4. 2. Externally fired gas turbine cycle based on biomass gasification gas as fuel

   Author : Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
   Keywords : Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

   Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE

5. 3. Combined heat and power plants in decarbonized energy systems: Techno-economics of carbon capture and flexibility services at the plant, city and regional levels

   Author : Johanna Beiron; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Negative emissions; Flexibility; CCS; District heating; Energy system modeling; Combined heat and power; Techno-economic assessment;

   Abstract : Our present energy system is the main driver of climate change. Variable renewable electricity generation and carbon dioxide removal (CDR) are key technologies in the transformation to a sustainable energy system, but their broad implementation implies challenges related to energy system flexibility and energy requirements of CDR technologies.

6. 4. High Temperature Oxidation and Chlorination of FeCrAl alloys

   Author : Niklas Israelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; KCl; pre-oxidation; FeCrAl; H2O; high-temperature corrosion; kinetics;

   Abstract : AbstractThe constant strive for improved efficiency and lower-cost industrial processes often results in progressively higher temperatures and more aggressive environments. High- temperature corrosion is a well-known problem in biomass- and waste-fired boilers and is one of the obstacles to overcome in achieving a more sustainable society. READ MORE

7. 5. Evaluating the utilisation of industrial excess heat from an energy systems perspective

   Author : Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

   Abstract : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. READ MORE
